Wow, HUGE TRADE!!!
Is this a valid offer or a trade you plan to propose? Obviously you would win this deal HUGE, even if Miller wasn't ever healthy again. Unless I'm missing something,
it's hard to believe the 7th place guy would give up that much. Perhaps he feels he JUST HAS TO HAVE Soriano for keeper purposes.
One thing I'd worry about, if you do accept this, it'll be frowned upon bigtime by the other league members. No one likes to see lopsided trades go down.
